Early Efficacy Observation of Pomalidomide-based Regimen in the Treatment of High-risk Multiple Myeloma
OBJECTIVE: To investigate the efficacy and safety of pomalidomide based regimen in the treatment of high-risk multiple myeloma (MM).
METHODS: Clinical data of 27 high-risk MM patients treated in Shanxi Bethune Hospital from January 2021 to December 2022 were retrospectively analyzed. All patients were treated with pomadomide based regimen for at least 2 consecutive cycles, and the early therapeutic effect and safety were observed.
RESULTS: Overall remission rate (ORR) was 63.0%(17/27 cases) and deep remission rate was 22.2%(6/27 cases) after 2 cycles of treatment; ORR was 90.5%(19/21 cases) and deep remission rate was 66.7%(14/21 cases) after 4 cycles of treatment. Both ORR and deep remission rate were significantly higher after 4 cycles of treatment than 2 cycles (P=0.044, P=0.003). Beyond that, in the newly diagnosed and relapsed refractory MM groups, ORR after 2 cycles of treatment were 75%(9/12 cases) and 60%(9/15 cases), and deep remission rates were 25%(3/12 cases) and 20%(3/15 cases), respectively; ORR after 4 cycles of treatment were 100%(9/9 cases) and 83.3%(10/12 cases), and deep remission rates were 77.8%(7/9 cases) and 58.3%(7/12 cases), respectively, while there was no significant difference in remission rates between the two groups (P>0.05). In the group of creatinine ≥177 μmol/L, the serum creatinine level was significantly decreased after 2 cycles of treatment compared with that pre-treatment (P=0.001). The 1q21 amplified subgroup accounted for the largest proportion (21/27 cases), ORR was 66.7%(14/21 cases) and deep remission rate was 23.8%(5/21 cases) after 2 cycles of treatment, ORR was 88.9%(16/18 cases) and deep remission rate was 66.7%(12/18 cases) after 4 cycles of treatment. In all the symptoms, the most common adverse reactions were pulmonary infection in 9 cases and hematological adverse reactions of grade 1-2 in 8 cases.
CONCLUSION: The pomalidomide-based treatment regimen has good early curative effect on the newly diagnosed and relapsed refractory high-risk MM, and also benefits to the high-risk cytogenetic MM, or MM with renal impairment. Therefore, this treatment regimen showed a good safety, and the long-term curative effect needs to be further assessed by more clinical data.
